First we take a can and fill it with 1 cm of water and heat it at a specified temperature then dip it in cold water,the can will crush.then we take out its volume by pouring water into the can .the amount of water in each will tell its volume and then we do the same with 4 cans and then plot a graph . verifying the temperature.
The independent variable in temperature.The pendent variable is volume. The control variable is intial water that is 1cm in can
